A shopkeeper marks the price of an article in such a way that after allowing a discount of 22%, he gets a gain of 11%.If the marked price is Rs.888, then the cost price of the article is:
Marked price = 888
Discount = 22%
Selling price = 888 $$\times$$ 78/100 = 692.64
Gain = 11% so selling price = 111% of cost price
692.64 = 111% of cost price
Cost price = 692.64 $$\times$$ 100/111 = ₹ 624
